For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Please refer to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: a small stand stacker with a cargo anti-dumping structure, comprising a vehicle frame 1, a gantry 12, a lifting assembly and a front shovel 7, wherein the gantry 12 is movably mounted on the front of the outer wall of the vehicle frame 1, a connecting frame 6 is movably connected and mounted on the front of the outer wall of the gantry 12 through a lifting assembly, a supporting frame 13 is movably mounted in the connecting frame 6 through a spacing adjustment assembly, a front shovel 7 is movably mounted on the front of the outer wall of the supporting frame 13 through a center of gravity stabilizing assembly, an extended anti-dumping assembly is fixedly mounted in the front shovel 7, and the extended anti-dumping assembly is used for anti-dumping limit protection according to the weight of the cargo; The extended anti-tilt assembly includes: a piezoelectric signal sensor 18, an electromagnetic driver 19 and a first motor 23; A piezoelectric signal sensor 18 is fixedly installed at the bottom of the inner wall of the front shovel 7, a grounding rod 16 is movably installed at the top of the outer wall of the piezoelectric signal sensor 18, a pressure plate 15 is fixedly installed at the top of the outer wall of the grounding rod 16, and a return spring 17 is surrounded by the outer wall of the grounding rod 16.

At this time, the reset spring 17 deforms and contracts, and the grounding at the bottom of the grounding rod 16 touches the grounding at the top of the outer wall of the piezoelectric signal sensor 18.

Further, when the forklift truck lifts the goods The infrared rangefinder 35 detects the lateral width data of the cargo by infrared ranging technology, calculates the spacing adjustment parameters and signals by a preset program algorithm, and sends the adjustment signal to the first air hydraulic cylinder 36. The first air hydraulic cylinder 36 is started, and the first air hydraulic cylinder 36 pulls the support frame 13 to move left and right on the sliding link 34 through the first hydraulic telescopic rod 37, thereby changing the spacing between the support frames 13, so that the front shovel 7 can lift the cargo to the edge point under the cargo to the maximum extent when forking the cargo, thereby ensuring that the cargo will not tilt or fall.

[0029] Working principle, first, the stacker detects the cargo width parameter through the spacing adjustment component and adjusts the spacing between the front shovels 7 to stably lift the cargo; Then, when the cargo is forked, the anti-tilt component is extended to limit and fix the cargo and lift it at multiple points. During the driving process of the stacker, the horizontal monitoring component monitors the possible tilting trend of the cargo caused by the vehicle turning and braking in real time, and feeds back to the center of gravity stabilization component and the brake cargo stabilization component in real time to fine-tune the center of gravity and ensure the stability of the cargo. Finally, when the vehicle reaches the stacking location, the lifting and stacking of the goods is completed through the lifting assembly.
